Process for effecting the relaxation of muscles of a human by means of fragrance

ABSTRACT

Described is a process for effecting the relaxation of a tensive back, shoulder or neck muscle of a human mammal for a substantial period of time. The process of our invention consists essentially of the step of continuously or periodically administering to said human mammal through inhalation over a stress reactivity-reducing, tensive back, shoulder or neck muscle-relaxing period of time, a stress reactivity-reducing, tensive back, shoulder or neck muscle-relaxing quantity and concentration of one or more fragrance compositions having an aroma profile including one or more of a rose, floral, musky, ambery, sweet and/or powdery aroma notes.

FIELD OF THE INVENTION

[0001] Our invention relates to a process for effecting the relaxation (i) to a substantially low stress-reactive state and (ii) to a substantially low tensive state, of at least one stress-reactive and tensive back, shoulder or neck muscle of a human mammal for a substantial period of time. The process of our invention consists essentially of the step of continuously or periodically administering to said human mammal through inhalation over a stress reactivity-reducing, tensive back, shoulder and/or neck muscle-relaxing period of time, a stress reactivity-reducing, tensive back, shoulder and/or neck muscle-relaxing quantity and concentration of one or more fragrance compositions having an aroma profile including at least one rose, floral, musky, ambery, sweet and/or powdery aroma nuance(s).

BACKGROUND OF THE INVENTION

[0002] Reactivity to stress is insidious because it does not directly incapacitate a human, but acts as a vector of extreme discomfort in various locations of the body of the human, e.g., back, shoulder and/or neck muscle pain and spasms which are a direct result of excessive back, shoulder and/or neck muscle tension brought about by the reactivity to stress.

[0003] The term “stress” hereinafter refers to an event or experience in life of an individual that has specific physiologic and/or subjective consequences that disturb the equilibrium of the individual (see Kopin, I. J., Definitions of Stress and Sympathetic Neuronal Responses Stress: Basic Mechanisms and Clinical Implications, Annals of the NY Academy of Sciences, G. Chrousos, R. McCarty, K. Pacak et al editors, New York, N.Y., New York Academy of Sciences 771: 19-30.). Sources of stress may be an individual's occupation or it may be a life event such as a change of job. The term “reactivity” hereinafter refers to the change generated by stress in the individual's physiologic and/or subjective condition. Within the context of this invention, the term “reactivity” may be ascertained (a) objectively, by measuring, using electrical measuring techniques, the degree of muscular back, shoulder and/or neck tension and (b) subjectively by use of self-report of various symptoms including degree of muscular back and/or neck pain and degree of muscular back and/or neck ‘tension’ and ‘relaxation’. Unlike a drug that is ingested orally or injected subcutaneously, the fragrance compositions utilized in the practice of our invention are inhaled. Hence, for the purpose of practicing this invention, the term “amount administered” hereinafter is intended to mean “amount of stress reactivity-reducing composition calculated to have been inhaled, retained, absorbed and/or provided into the blood-stream”.

[0004] Methods for reducing physiological and/or subjective reactivity to stress in humans being subjected to stress conditions by administration of stress reactivity-reducing substances such as nutmeg oil, orange oil and valerian oil through inhalation are well known in the prior art, for example, Warren et al, U.S. Pat.

Although Librizzi et al. indicates at page 3: “The term ‘administering’ refers to (i) inhalation of a topically applied personal care composition . . . ”, the Librizzi et al. published PCT Patent Application does not, however disclose or suggest the method of inhalation therapy to induce muscle relaxation, and furthermore, no disclosure or suggestion of any methods for the causation of back, shoulder and/or neck muscle relaxation or significant reduction of back, shoulder or neck muscle tension is set forth therein.

[0016] is disclosed by Price, S. and Price, L. in “Aromatherapy for Health Professionals” © Harcourt Publishers Limited 1999, Chapter 12, “Stress”, pages 207-215. The Price, et al. publication does not, however, explicitly or implicitly disclose the method of inhalation therapy to induce muscle relaxation.

[0017] Accordingly, a need exists for a process for effecting the relaxation to (i) a substantially non stress-reactive state and (ii) a substantially non-tensive state of at least one stress-reactive and tensive back, shoulder or neck muscle of a human mammal for a substantial period of time, using one or more specifically-designed fragrance compositions to be conveniently administered by means of inhalation.

SUMMARY OF THE INVENTION

[0018] Our invention is directed to a process for effecting the relaxation to (i) a substantially low stress-reactive state and (ii) a substantially low tensive state, of at least one stress-reactive and tensive back, shoulder or neck muscle of a human mammal for a substantial period of time. Such back, shoulder or neck muscles include, but are not limited to upper layer muscles such as the Splenius capitis muscle, the Splenius cervicus muscle, the Levator scapulae muscle, the Rhomboid major muscle, the Supraspinatus muscle, the Erector spinae muscle, the Trapezius muscle, the Serratus anterior muscle and the External oblique muscle; intermediate layer muscles such as the Rectus capitis posterior major muscle, the Longissimus captis muscle, the Spinalis thoracis muscle and the Iliocostalis lumborum muscle; and the deep layer muscles such as the Rectus capitis posterior minor muscle, the Interspinalis cervicis muscle, the Levator costae muscle, the Longus rotatores thoracis muscle, and the Quadratus lumborum muscle. The process of our invention consists essentially of the step of continuously or periodically administering to said human mammal through inhalation over a stress reactivity-reducing, tensive back, shoulder and/or neck muscle-relaxing period of time, a stress reactivity-reducing, tensive back, shoulder and/or neck muscle-relaxing quantity and concentration of one or more fragrance compositions having an aroma profile including at least one rose, floral, musky, ambery, sweet and/or powdery aroma fragrance notes or nuances.

[0019] More particularly, our invention is directed to a process for effecting the relaxation to (i) a substantially low stress-reactive state and (ii) a substantially low tensive state of at least one (M) stress-reactive and tensive back, shoulder or neck muscle of a human mammal having a weight, W, of from about 50 pounds up to about 300 pounds, each of which back or neck muscle has an initial magnitude of tension, δ_(io) microvolts, in the range of from about 0.5 microvolts up to about 10.0 microvolts for a substantial period of time, Δθ, preferably from about 1 minute up to about 24 hours, consisting essentially of the step of continuously or periodically administering to said human mammal through inhalation over a stress reactivity-reducing, tensive back, shoulder or neck muscle-relaxing period of time, (Δθ)′, preferably from about 1 minute up to about 24 hours, a stress reactivity-reducing, tensive back, shoulder or neck muscle-relaxing (i) quantity, Q, preferably from about 6.0 nanograms up to about 500 micrograms; (ii) concentration, C, preferably from about 1 nanogram per liter up to about 125 micrograms per liter and (iii) inhalation rate, ∂Q/∂θ, (the partial derivative of quantity of fragrance inhaled with respect to time of inhalation) preferably from about 1 microgram/hour up to about 45 milligrams/hour, of one or more fragrance compositions of matter having an aroma profile selected from the group consisting of rose, floral, musky, ambery, sweet and powdery, wherein the resulting relaxation effect has a magnitude R>10 on a scale of 1-100 and the resulting magnitude of back, neck and/or shoulder muscle tension, δ_(if) is in the range of from about 0.4 microvolts up to about 3.3 microvolts and wherein δ_(io) is greater than at least about 1.05 δ_(if) microvolts, preferably greater than about 1.10 δ_(if) microvolts, and most preferably greater than about 1.25 δ_(if) microvolts.

[0020] Other preferred embodiments of the present invention include the use of fragrance for immediate relief by providing fragrance in higher concentration for a short period of time to longer lasting applications where fragrance at a lower dosage is provided for extended periods of time. Fragrance may be provided in duration as short as about 30 seconds to as long as about 24 hours, preferably such as from about 2 minutes to about three hours. The amount of fragrance provided can be at levels ranging from about 1 microgram to about 100, preferably from about 10 to about 50 micrograms/liter of air inhaled by the subject.

[0021] The aforementioned process may be further defined as involving a mathematical relationship wherein

R=f(W, δ _(io), δ_(if), Δθ, (Δθ)′, C, ∂C/∂θ, Q, ∂Q/∂θ)

[0022] and in addition, the process may be based on the algorithm:

ΔR=k ₁ ∫∫∫W(∂C/∂θ)(∂Q/∂θ)(∂[Σ{δ_(io)−δ_(if)}]/∂θ)dθdθdθ+k ₂(Δθ){(Δθ)′}

[0023] wherein ∂C/∂θ represents the partial derivative of concentration of fragrance composition inhaled with respect to time; wherein k₁ and k₂ are constants of integration and wherein the term: τ{δ_(io)−δ_(if)} is a summation in units of microvolts for M back, shoulder and/or neck muscles where 1≦M≦M_(max) with M_(max) being the maximum number of back, shoulder and neck muscles in a human mammal.

[0024] As used herein the fragrances of rose, floral, musky, ambery, sweet and or powdery is understood to mean a fragrance composition that a person with ordinary skill in the art would recognize as having the characteristics of these well known fragrances. The fragrances of the invention are not limited to those fragrances that have these characteristics alone, but also includes fragrances as having these notes or nuances in the fragrances and which provide the muscle relaxing characteristics described herein.

Testing Protocol

[0028] Objective: To demonstrate that specific fragrance formulations provide back and/or shoulder and/or neck muscle relaxation during stress as compared with an unfragranced control.

[0029] Summary of Study: Three research studies were conducted, each using different fragrance formulations diluted in odorless diethyl phthalate (hereinafter referred to as DEP). Stress was induced in these research studies by means of the Stroop task. The Stroop task is a performance task that involves the naming of the typeface color of each of a series of words presented once per second on a computer screen when the words themselves are color names that conflict with the typeface color. The stress level of the task is enhanced at the ‘halfway’ point by moving the position of the word around on the screen and adding sound effects to each word presentation, such as breaking glass and screeching car brake effects. Subjects are also told that their performance is being tape-recorded, and a microphone is pointed out to them. The effect of a fragrance composition on the muscle is determined by comparing the muscle response to the Stroop task in a group of subjects who are exposed to the diluted fragrance composition by inhalation to a group of subjects who are exposed to the odorless diluent only.

[0030] Subjects: For the research studies subjects were right-handed female adults, aged 25-50, English first language, not currently taking prescribed medications (with the exception of birth control medications, anti-histamines and over-the-counter medications) and free of medical history of cardiovascular or other serious disease, and free of psychological/psychiatric history. The subjects had a median age of 41. In each study subjects were divided into two groups, a Fragrance group and a Control (DEP) group, as more particularly described herein.

[0031] Experimental Protocol: The Fragrance group in Study 1 received Fragrance A (n=15), as more particularly described in Example I, herein. The Fragrance group in Study 2 received Fragrance B (n=20), as more particularly described in Example II, herein, or Fragrance C (n=20), as described in Example III, herein, or Fragrance D (n=20), as described in Example IV, herein. The Fragrance group in Study 3 received Fragrance E (n=5), as more particularly described in Example V, herein, or Fragrance F (n=7), as described in Example VI, herein. In Studies 1 (n=15), 2 (n=20), and 3 (n=6) the unfragranced Control group received only odorless DEP. In all three studies each subject was tested individually in a single session. Subjects were told the general nature and course of the study, namely: “how well people perform on different mental tasks in the presence and absence of fragrance. The fragrances in the study range anywhere between strong, moderate and weak, and none of them are unpleasant.” For Studies 1 and 2 a measure of back and/or shoulder and/or neck muscle activity was taken from a pair of electrodes placed on the upper back, near the spine, as shown in FIG. 1A. For Study 3 an additional measure of back and/or shoulder and/or neck muscle activity was taken from a second pair of electrodes placed on the upper shoulder, as shown in FIG. 1B. Both placements lie on top of the large, fan-shaped Trapezius muscle, which connects the shoulder to the spine from the neck to the mid-back. The sensors measure the electromyogram (EMG) from underlying muscles, including the Trapezius and other deeper muscles, including but not limited to upper layer muscles such as the Splenius capitis muscle, the Splenius cervicus muscle, the Levator scapulae muscle, the Rhomboid major muscle, the Supraspinatus muscle, the Erector spinae muscle, the Trapezius muscle, the Serratus anterior muscle and the External oblique muscle; intermediate layer muscles such as the Rectus capitis posterior major muscle, the Longissimus captis muscle, the Spinalis thoracis muscle and the Iliocostalis lumborum muscle; and the deep layer muscles such as the Rectus capitis posterior minor muscle, the Interspinalis cervicis muscle, the Levator costae muscle, the Longus rotatores thoracis muscle and the Quadratus lumborum muscle.

[0032] After the sensor placement, the experimenter went to an adjoining room where the psychophysiology monitoring equipment, described herein, was located. The experimenter could view the subject through a one-way mirror. Initially there was a series of practice trials, lasting in total approximately 30 minutes, in which the procedures of the baselines and Stroop test were presented to subjects in order to allow them to adapt to the procedures. After this the experimenter entered the room and introduced the fragrance. Fragrance A was a fragrance composition diluted at 20% by weight in DEP. Fragrances B-F were all fragrance compositions diluted at 10% by weight in DEP. The Control substance was pure DEP. The experimenter uncovered a 250 ml wide-mouth jar filled with 100 ml of liquid and placed it about 1 meter in front of the subject on a table. A small fan was turned on next to the jar and pointing towards the subject, blowing across the top of the jar towards the subject.

[0033] For all studies the experiment consisted of a Rest period followed by the Stroop task period, followed by a Recovery period. Each period was 3 minutes in duration. The Rest period was a baseline condition in which each of the subjects observed a series of colored squares presented at an easy-to-follow rate of 10 sec. per stimulus. Each subject's task was merely to count the number of squares of a particular color. This relatively elementary task effectively allowed each of the subjects to rest yet insured that each of the subjects was alert. The Stroop task was the stress condition, as described herein. The Recovery period was essentially the same as the baseline Rest, in which subjects performed another elementary colored squares counting task. Study 2 and 3 contained an additional period not used in Study 1, namely an “Eyes-Open” (EO) Rest period of 3 minutes duration that preceded the baseline Rest period.

[0034] EMG recording and data analysis: Trapezius EMG was recorded using a J&J Physiolab I-330 C-2 system (J & J Engineering Inc., 22797 Holgar Ct. NE, Poulsbo, Wash. 98370). EMG signals were integrated and averaged to provide a mean value (in microvolts) for each of the 3 minute epochs.

[0035] For each Study the epoch preceding the Rest period was compared statistically to the Rest period, and was found to be not significantly different (p's>0.3). In Study 1 this preceding period was a colored square recovery period (3 minutes in duration) from the practice Stroop task. In Studies 2 and 3 the preceding period was the “EO Rest” period. For Studies 1 and 2 the EMG activity during this preceding rest period was used as a covariate in a repeated measures analysis of covariance of the Rest, Stroop, and Recovery period means. Use of a covariate allows individual differences in resting value to be statistically removed from comparisons among conditions and between groups. This permits a more sensitive (statistically powerful) test of the treatment effects. Significance was set at the 0.1 level for the between-group difference or the between-group by condition interaction. The results of Study 3 were not statistically analyzed due to the small group sizes involved.

[0036] Study 1 and 2 Results: The Group X Period interaction was significant for Study 1 comparing Fragrance A to DEP (F[2, 25]=2.81, p=0.079) and for Study 2 comparing Fragrance B to DEP (F[2, 36]=2.53, p=0.094). As shown in FIG. 2, described herein, in FIG. 3, described herein, and in Table 2, herein, the Fragrance condition demonstrated reduced stress-reactive EMG increases as compared with the unfragranced Control condition. For Fragrance A, this reduction was 62.6% and for Fragrance B, this reduction was 39.6%. In contrast, Fragrance C and Fragrance D actually increased the stress-reactive EMG tensive response compared to DEP, by 162.5% and 95.0%, respectively, as shown in FIG. 4, described herein, and in Table 2, herein.

[0037] Study 3 Results: These results are based on a small sample size (n<10), hence statistical analysis was limited to inspection of means. Fragrance E lowered both upper and lower Trapezius muscle stress-reactive tensive activity by 65.3% and 64.7%, respectively, as shown in FIG. 5 and FIG. 6, described herein, and in Table 3, herein. Fragrance E thus effects relaxation for both the upper Trapezius and lower Trapezius muscles. In contrast, Fragrance F increased the stress-reactive EMG tensive response compared with DEP for both the upper and lower Trapezius muscles by 28.5% and 0.8% respectively as shown in FIG. 5 and in FIG. 6 described herein and in Table 3, herein.
